Abstract

The conversion of solar energy into electrical energy using Photovoltaic monocrystalline modules is an alternative power plant that is pollution-free and environmentally friendly. Indonesia is a subtropical area that is rich in sunlight, which is the main raw material for PV. The energy conversion process in PV is strongly influenced by an increase in temperature that exceeds the threshold, which will cause a decrease in PV efficiency. Increasing the efficiency of PV has been done by many researchers from various countries, previous studies mostly used force convection or active cooling methods by adding cooling fans, spray water, heat sinks that require additional energy, problems that arise are how to improve photovoltaic efficiency without adding any extra energies? In this research, increasing the efficiency of PV using the free convection or passive cooling method, designing a perforated aluminum plate that is installed next to the bottom of the PV panel by designing holes 15mm in diameter and 20 mm apart. The idea of this research is something new and has a contribution to science, so it is very necessary to do this research in developing new and renewable technologies.

Abstract

Pemulutan village has a location that is separated by a small river, where only one of its locations has access to PLN electricity rom the government. The portable hybrid on grid system PV-PLN-Generator has the ability to combine a power source from PLN with alternative sources of electricity from solar panels and generators, this system was applied in this study by adding a portable system, so that it can be carried and moved easily from opposite locations of river. The ouput power of one solar panel is about 20-25 W, so it takes 6-7 solar panels to be used with load 70 Watt for 12 hours. The results of this research are very helpful for Pemulutan’s village, with the portable hybrid on grid (PHoG) system can help access electricity for lighting, process garden products, and relieve the cost of charging PLN electricity.

Abstract

Abstract Photovoltaic (PV) is a power plant that converts solar radiation into electrical energy through the photovoltaic effect, where the process of generating electrical energy is affected by one factor, that is, an increase in temperature exceed. Excessive temperature rise leads to reduced PV efficiency. More temperature monitoring is required to maintain PV performance, typically, more temperature measurements are constrained by distance, in real time, automatically. The original idea of ​​the author was to use IoT with thinger.io internet application with unlimited remote installation. Thinger.io is an open source platform in IoT used as a user interface or data visualization during monitoring. The monitoring in this study will detect excessive temperature, as well as voltage, current, and solar radiation parameters using an IoT-based application compared to conventional measurements using data loggers. have error rate. The results show that the overheating message only appears when the PV temperature is equal to or above 450C and repeats when the temperature decrease below 450C and then increase again to exceed 450C, the average percentage error is 0.016%, 0.107%, 0.006% and 0.008%.

Abstract

The Solar Guardian application was developed as a real-time monitoring solution for rooftop solar power plants to improve system efficiency and reliability. This study evaluates the performance of Solar Guardian in recording and analyzing the main parameters of a polycrystalline panel-based solar power plant with a maximum power of 100 Wp, a maximum voltage of 20 V, and a maximum current of 5.5 A. This system uses a 100 Ah VRLA battery, with monitoring of the panel output voltage, battery charging and discharging current, and energy storage efficiency. The results show that Solar Guardian is able to increase the efficiency of solar power plant monitoring by up to 20%, with early detection of system anomalies, such as decreased solar panel performance and power imbalance in the battery. This application also allows users to access operational data in real time through a cloud-based interface, making it easier to manage power and optimize energy utilization. In addition, the integration of IoT technology in Solar Guardian allows automation in data recording, thereby reducing delays in maintenance decision making. With the implementation of this application, solar power plants can operate more stably, increase energy storage efficiency, and optimize carbon emission reductions of up to 35.86 kg CO₂ per day.

Abstract

Kebutuhan energi listrik di sektor pendidikan terus meningkat, seiring bertambahnya aktivitas dan operasional kampus. Di sisi lain, penggunaan energi fosil yang berkelanjutan berdampak buruk pada lingkungan. Oleh karena itu, pemanfaatan energi baru terbarukan, khususnya energi surya, menjadi solusi yang layak dan ramah lingkungan. Penelitian ini bertujuan untuk merancang dan menganalisis sistem pembangkit listrik tenaga surya (PLTS) on-grid di Gedung KPA Universitas Sriwijaya. Metode yang digunakan mencakup pengukuran konsumsi energi gedung, pengujian output panel surya, serta perancangan sistem dengan pendekatan teknis dan ekonomis. Hasil pengukuran menunjukkan bahwa konsumsi listrik tahunan gedung sebesar 216.344,128 kWh. Sistem PLTS dirancang untuk menyuplai 10% dari kebutuhan tersebut dengan 300 panel surya 100 Wp, menghasilkan daya total 30 kWp. Estimasi produksi energi selama 25 tahun mencapai ±553.000 kWh. Analisis keekonomian menunjukkan sistem mampu memberikan keuntungan bersih sebesar ±Rp 160 juta, dengan estimasi penghematan bulanan ±Rp 1,6 juta. Hasil penelitian ini membuktikan bahwa sistem PLTS on-grid layak diterapkan secara teknis dan ekonomis di lingkungan kampus sebagai bagian dari transisi energi bersih dan strategi efisiensi biaya operasional.
